this is immersive portals on 1.20.1 with sodium 0.5.11.
these potential solutions suck. ideally it would tell me to either:
- replace Sodium 0.5.11 with Sodium 0.5.3
- or to find a version of immersive portals that is compatible with sodium 0.5.11
the 'more details' section isn't great either but that's been reported many times now too. #386 (comment)

this part in particular often trips users up

Immersive Portals has "breaks": { "sodium": ["<0.5.3", ">0.5.3"] }
